Greg,
Hey man not sure what your mounting is but if you are replacing motor
and driver combo like I did you can get some decent motor setups from
Machmotion.com. They are made by Teco and they sell mitsubishi and another
brand I think. I used the Teco models on all three axes and they are
pretty good especially for the money. I used the 5nm motors with 1000RPM
for X and Y on my machine. They are 130mm mounting not sure what you have.
You need to do some research into the factory motors power and speed and
mounting bolt pattern and style. Here is a link to mine. Very happy with
them so far. Peace

Get your SQL database under version control now!
Version control is standard for application code, but databases havent
caught up. So what steps can you take to put your SQL databases under
version control? Why should you start doing it? Read more to find out.
